Product description

The filter film reduces the emitted energy evenly across the entire spectrum, allowing longer exposure times with cameras with slow shutters or very fast systems. The ND film is simply inserted into the frame of the Aurora Flatfield and remains there.

With combinations of the three densities (ND 0.6, ND 0.9 and ND 1.2), the brightness of the Aurora can be adjusted very precisely to the recording system.
